Abstract

In this paper，the traditional three-dimensional space vector pulse width modulation (3D-SVPWM) al-
gorithm is deeply analyzed，and it is proved that the traditional algorithm can be simplified． Then，an optimized 3D-SVPWM algorithm is proposed． In comparison with the traditional algorithm，the optimized algorithm becomes extremely simplified and can guarantee the system performance． Moreover，it effectively reduces the complexity and the computation amount，and improves the instantaneity and the stability，which helps to alleviate the software load and thus provides more space for other control algorithms in the system． Finally，the feasibility and superiority of the proposed optimized algorithm are verified through the simulation and experiment in a three-phase four-wire center-spilt shunt active power filter．

Key words：  three-dimensional space vector pulse width modulation; simplified algorithm; active filter
